The drama — which followed on from epic battle between Daenerys Targaryen (Emilia Clarke) and the Lannisters — moved thick and fast through the burned out aftermath of the action to Jon Snow’s plan to confront the army of the dead.

In fact, the episode moved so fast that some fans began to question the pace.

Others seemed baffled by the intricacies of the plot, with a viewer tweeting: “Game Of Thrones is the only show I know that assigns homework. An episode is followed by 2 hours of internet reading to knit it all together.”

The action lurched from one character to another with fans particularly thrilled about the return of Gendry (Joe Dempsie) — the blacksmith and bastard son of the late King Robert Baratheon.

One fan wrote: “Been waiting for Gendry to come back for so long,” while other fans pleaded for producers to keep the character alive, despite his plans to travel north of The Wall with Jon.

“Don’t go killing off Gendry now” one viewer begged.

Meanwhile, arguably the biggest bombshell was dropped by Sam Tarly’s girlfriend Gilly, who revealed that Jon Snow might not be a bastard after all.

She asked Sam: “What does annulment mean?” before reading in a Maester’s document that someone called Prince Rhaegar, had an annulment and married someone else in a secret ceremony.

Fans were quick to point out that Daenerys’s brother Rhaegar could have annulled his first marriage to marry Lyanna Stark, Jon Snow’s mother.

Incredibly, this could mean that the newly legitimate Jon Snow has a claim to the Iron Throne.
